Ecosystem Roles and Energy Flow

The video explains how organisms in an ecosystem obtain energy, highlighting the roles of producers, consumers, and decomposers. Producers, mainly plants, create food through photosynthesis. Consumers, including herbivores, carnivores, and omnivores, obtain energy by eating other organisms. Decomposers, such as bacteria and fungi, break down dead matter, recycling nutrients back into the ecosystem. The video encourages viewers to explore their local ecosystems to identify these roles.
